### Search before asking - [X] I searched in the [issues](https://github.com/apache/incubator-paimon/issues) and found nothing similar. ### Motivation Currently, the `FileStoreExpireImpl` delete file quietly, which means if there occurs error, the process won't throw exceptions. It's possible that some files won't be deleted when snapshot expiring, so I propose to introduce an action to clean files unused by current snapshots. ### Solution Scan all files and filter out that still used by at least one snapshot, then delete those not used by any snapshot. ### Anything else? _No response_ ### Are you willing to submit a PR? - [X] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
